切换界面时界面刷新慢，怎么解决

Question

觉得一般情况下不会这么离谱。建议排查一下程序，比如是否在Paint事件中做了什么动作。

Answer 1

load事件和构造方法检查一下，估计是程序问题，我们用过4个tab的也不慢

Answer 2

我觉得有可能是系统的问题，没听说过切换个tab，还卡的。
你放到另一台电脑上看看还卡不卡

Answer 3

程序已经被我简化成最简单了，只有三个文件，出了设置双缓存代码以外，没有任何自写的代码了：
Program.cs文件：using System;
using System.Collections.Generic;
using System.Windows.Forms;namespace HMI
{
    static class Program
    {        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MainForm());
        }    }
}
文件MainForm.cs：using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Reflection;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
namespace HMI
{
    public partial class MainForm : Form
    {        public MainForm()
        {
            InitializeComponent();
            #region 设置双缓存，解决闪烁问题
            //Type type = tabPage1.GetType();
            //PropertyInfo pi = type.GetProperty("DoubleBuffered", BindingFlags.Instance | BindingFlags.NonPublic);
            //pi.SetValue(tabPage1, true, null);            this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.DoubleBuffer, true);// 设置双缓冲，防止图像抖动,忽略系统消息，防止图像闪烁
            #endregion
        }        private void MainForm_Load(object sender, EventArgs e)
        {        }        private void MenuItemExit_Click(object sender, EventArgs e)
        {
            this.Close();
        }          }
}

Answer 6

首先把业务都去掉。看一看速度。
就是frm_Load或者其他内容的都注释掉，一步一步看哪里问题。

Answer 7

谢谢各位，受限于论坛只能连续发3个回复，代码没有发完全。今天继续。
另外要强调一下的是，界面构造函数和Load函数中可以说几乎没有自己写的代码，别的地方也没有代码，可以说就是一个原始的界面设计。但在进行程序切换或tab切换时能明显感觉到闪烁。文件MainForm.Designer.cs续：

}论坛有没有上传附件的功能？
在回复里上传代码太麻烦了，稍微复杂点的界面就超过10000字符了，再加上只能连续3次回复的限制，上传代码好麻烦啊。

Answer 9

同一个界面上的控件太多了 winForm就是这样的 尝试重新布局控件，比如做做分组，放在不同的TabControl页中。

Answer 10

GDI的性能本来就不高，你也可以测试用WPF来开发你的应用。

Answer 11

偶用的是VS2005，.net 2.0。WPF是.net3.0的容。现在VS2005是不是太落后了。

Answer 12

winform 的特点， 如果你一定要在同一个窗体上放这么多控件，那估计没什么好办法解决

Answer 13

是在没办法，只好自己习惯了。
有人说WPF更慢，不知是不是真的？
